IMPROVED GAR-BRAKE 'd'blgt tl1tlmlt arms-m in these 322m Qatari antmakiuggart of It: same,

L TO ALL WHOM IT MAY CONCERN: v

Be it known that I, SAMUEL M. LEE, of New London, in the county ofHenry, and State of Iowa, have invented a new and useful Improvement inSelfActing Railroad-Car Brakes; and I do hereby declare the fol-' losingto' be a full and correct description thereof, suflicient to enableothers skilled in the art to which my invention appertains to fullynnderstandits construction and operation, reference being had to theaccompanying drawings, which make part of this specification, and inwhich Figure l is a side elevation of a train, and

Figure 2 a bottom view of the tender and one car provided with myimproved brake.

Like letters indicate like parts in both figures. Y

The self-acting car-brake, heretofore patented require considerablealterations in the cars to which they are to be attached, and are inthemselves so complicated as to make it a matter of so great expense toapply them, they getting very often out of order, thatit is no advantageto the railroad-companies to bny the right to apply them.

-My improved brake-device can be attached to any car now in use on anyrailroad, without the necessity of ehangingthe brake-gear on them, andconsists in the attachment of the broke in a peculiar manner to abrakebar running under the car, from end to end, in a line parallel tobut not in the centre line. of its bottom, said brake-bars beingoperated by a cylinder-placed under the foot-boardofthelooomotive-engine in such a manner that theengineer can set andrelease the brakes at will.

A, in the drawings, may represent the locomotive,

B the tender, and

C one track of a passenger or freight-car of train.

Under the foot-hoards of the locomotive. is arranged a cylinder, D, thepiston d of which operates on the brake-bar b of the tender, and isconnected with the steam in'the boiler by a pipe, a.

On the under side of the bottom of the tender B, a forked brake-bar, 6,operates in proper bearings, the space between theforksb of which is inthe centre of the bottom of the tender.

The brake across bar e has pivoted to it a lever, a, one end of which isconnected to one of the forks 6', while the other is connected to theother brake cross-barf.

On the under side .of the bottom of the truck C is a brake-bar, c,sliding in proper hearings, in snob a manner as to correspond witheither fork b oftlie brake-bar 6, according to the position the caroccupies to the tender. To this bar is connected, by a chain, 9, one endof a lever, 71, which is pivoted in the centre of the under side of thecar, as shown at 2', and the other end of which is again connected tothe other side of the has" 11 by a chain,j, and is also connected to thebrake-gear of the track by the rod is.

The brake-bars b c are of such length only as not to touch when thebumpers meet in backing up the train, and ei'rtends the whole length ofthe cars, one bar operating the brake-gears of both trucks of the samecar.

Its operation is very simple. When it is desired to set the. brakes up,the engineer admits steam into the cylinder D, thus forcing the pistonhack on the brake-bar b of the tender, one of the forks b of which againacts on the bar 0 of the car, and so on from car to car, so that allbrakes are set simultaneously and instantaneously. The engineer can, ofcoarse, graduate the degree of pressure to be exerted on the brakes bythe amount of steam let into the cylinder D, which latter is properlyprovided with exhaust-pipes, &c.

It will be easily seen that by the peculiar attachment of the brake-barc to the lever h, the brake-gear can be operated the same, no matterwhat end of the car is next to the tender.

Cars are hardly ever changed end for end on the track, but thelocomotive and tender are, and tar that reason I employ the forked arms15 of the brake-bar b.

It will be seen that this brake-device is very easily attached to anycar now in use, and can be constructed at .verv little cost.

I am aware the; it isnot new to operate brakes by means of a piston andsliding rods with ihtermediate levers. Such parts I do not,v therefo're,claim butvhaving thus described my invention,-

What I claim as new, and desire to secure by Letters Patent, is Incombination with an independent piston, 11, the arrangement of a forkedbay, 6, with thwtender, and a single bar, c, with the car, fat-operatingsaid bar a at either end, substantially as and for the purposedescribed.

To the above I have signed my name, this 28th day of February, 1868. I

' SAMUEL M. LEE.
